Electrical WiringChapter 3

WARNINGWARNING High Voltage: Disconnect power before servicing.WARNING

All wiring should be installed in accordance with National, State, and Local electrical codes. Fans used to ventilate livestock buildings or other rooms where continuous air movement is essential should be connected to individual electrical circuits, with a minimum of two circuits per room. For electrical connection requirements, refer to diagram on motor nameplate and to information enclosed with the Munters environmental control to be used.

Single Phase Fans: motor overload protection should be provided for each fan. A Circuit Breaker Switch or slow blow motor type fuses must be used See Figure 4A. See Munters form QM1400 for proper size.

Recommended wire routing:As the power cable exits the back of motor form a drip loop and then run power cable down along strut and "zip tie" the cable to strut to prevent cable from getting tangled in the pulley or belt. See figure 5. Then run the cable out the hole to the circuit breaker or control panel.

NOTE: A safety cut-off switch should be located adjacent to each fan.

Three Phase Fans: motor overload protection should be provided for each fan. A three-pole motor starter or slow blow motor fuses must be used. See Figure 4B. If a frequency drive (inverter) is used, confirm that motors are rated for inverter duty at the voltage used. The installation of line reactors is recommended to reduce voltage spikes and harmonic distortion. Supplemental motor overload protection is also recommended.

OperationChapter 4

1) INITIAL START-UP: With electrical power off, verify that the fan propeller turns freely and that all fasteners are secure. Turn on electrical power and confirm that the fan operates smoothly.

2) ADJUSTMENTS: Set the fan control to the temperature shown on your Munters drawing, or to a value which will provide the desired environmental conditions.

3) BELT ADJUSTMENTS: After 3 days of operation you must tighten fan belt. See Maintenance Section: Belt Tightening.

Single Phase Fans: When variable speed controls are used, the fan's idle speed will need to be set to the recommended minimum airflow rate. Refer to the procedures included with each control. The table below provides airflow rates at various propeller speeds for fans wired for 240 VAC.

Three Phase Fans:

1) 36" Direct Drive, 3 Phase fan is not suitable for frequency drive.

2) The use of a quality frequency drive and the installation of line reactors is recommended to reduce voltage spikes and harmonic distortion.

3) Minimum operating frequency of 30 Hz.

4) Will require three pole contactors with overload protection (by others).


MaintenanceChapter 5

WARNING


WARNING High Voltage: Disconnect power before servicing.WARNING

The following inspection and cleaning procedures should be performed monthly:

1) INSPECT PROPELLER: Check that propeller is secure on motor shaft and that there are no signs of damage. The blades are of a self-cleaning design and should not require maintenance.

2) CLEAN regularly for best results: • FAN MOTOR: Remove any dust accumulation from motor using a brush or cloth.

(DO NOT use a pressure washer). A clean motor will run cooler and last longer. At the same time, verify that the motor is secure in its mount.

• SHUTTER: Carefully clean dust from shutter blades and frame so that shutter opens and closes freely. A brush or cloth should be used.

• GUARD: Clean any dust or feathers from fan guards using a brush. Dirty guards can reduce airflow.

3) CHECK FASTENERS: For safety, all fasteners should be inspected. Tighten any loose connections.

4) INSPECT FAN CONTROL: With power disconnected, inspect all electrical connections. Wiring should be secure and in good condition. Remove any dust build-up from control case and sensor using a soft brush or cloth. NEVER CLEAN ELECTRICAL EQUIPMENT WITH A PRESSURE WASHER!

5) GREASE BEARINGS: Grease bearings every 4-6 months. Use no more than 2 shots when greasing fan. • A premium non-water based grease is recommended: - Shell Alvania #2 - Mobil Mobilux #2 - Exxon Unirex N2 - Texaco Premium RB - Mobil 532 - Texaco Multifak #2

6) CHECK DRIVE ALIGNMENT: Use a straight edge to check the alignment of the pulleys. If an adjustment is needed, remove the belt, then loosen the set screw in one pulley and move it. Remember to tighten the set screw after making an adjustment. Drive alignment is very important for long belt life and proper operation.

7) CHECKING PULLEYS: Roll the belt off and look at both pulleys. If the pulley has grooves in it or is no longer smooth, it needs replacement. A loose or slipping belt will reduce fan performance up to 60% and cause premature belt failure.

Maintenance / Winterizing FanChapter 5

8a) BELT tightening: All belts must be checked for proper tension after the first 3 days of fan operation and

every 4-6 months thereafter.

AeroLink Belt • Roll the belt off the pulleys by forcing it side ways off the larger pulley as you turn the drive by hand. • Reinstall the belt by wrapping it around the smaller pulley and then starting it over the larger pulley. • As you continue rolling it onto the larger pulley, the belt should become taut in the position shown below. • If the belt becomes taut before reaching the position shown, add one link and try again. • If the belt is loose when in the position shown, remove one link and try again.

8b) BELT tightening: To adjust the belt tensioner to the proper setting, loosen 10 mm bolt (using 16mm or 17mm end wrench)

to allow tensioner arm to rotate. Working from inlet/motor side of fan, place a 27 mm (11⁄16”) wrench onto the hex on the tensioner. Turn wrench clockwise until the single mark on base of the belt tensioner is aligned with mark 2 on the tensioner arm. Hold tensioner at this setting and tighten the 10mm bolt to 40 ft.-lbs torque

In most climates, it is probable that the ventilation system will never need to operate at a total capacity during the colder winter months. Consequently, it is advisable to "winterize" those fans which will not be used in cold weather to avoid unnecessary heat loss and condensation.To winterize, turn fan control "off". Install the insulated closure panel over the fan intake. If you don't have an insulated closure panel, a piece of rigid insulation material can be used. Remember the insulation panel must be removed before warmer weather returns.

NOTE: At least one single speed fan should be left uncovered and with power available to provide air movement in the event of variable speed control difficulties.
